A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which proceed by listing the objects that a term describes).
Fixed term means that the employee is employed for a specific period of time or task, for example a 6 or 12 month period, and employment ends on the date specified in the contract.
